Description

The present invention relates to a smart display mat that has improved safety and ease of wearing, can be made thinner, and has an energy-saving effect.

Currently, light emitting car floor mats on the market usually need to be electrically connected to a car power supply, which is very difficult to install and has safety issues, or By design, the volume is large, the weight is heavy, and there are few variations.

Further, in the conventional scuff plate, the on and off of the light (for example, an illumination lamp or a light emitting diode) is controlled by a magnetic switch, an infrared switch or an ultrasonic switch.

In the case of a configuration controlled by a magnetic switch, a magnet is provided on the door, and a floor mat is installed in a low place that can be seen when the door is opened, and both are turned on or off by magnetic sensing, so power can be saved, but a magnet for the sensing switch. Since it is difficult to attach the magnet and it is easy to shift, the detection accuracy may decrease.

In the case of a configuration controlled by an infrared switch or an ultrasonic switch, an in-vehicle power supply must be used, so an in-vehicle electric wire member for connecting parts is required, which makes installation complicated and also for safety. Problems arise.

Therefore, in either of the conventional car floor mats or scuff plates equipped with a light emitting function, it is necessary to electrically connect to the car power supply by an electric wire member in the mounting form, so that the mounting is complicated and there is a drawback in safety. Furthermore, it becomes impossible to realize a thinning of the entire car floor mat or scuff plate.

How to solve the above problems was the research and improvement theme of related engineers in this field including the inventor of the present application.

In order to solve the above problems, the main object of the present invention is to provide a smart display mat with significantly improved safety.
Another object of the present invention is to provide a smart display mat with greatly improved ease of wearing.

Another object of the present invention is to provide a smart display mat that has been made thinner.
Another object of the present invention is to provide a smart display mat that realizes an energy saving effect.

In view of the above object, the present invention includes a smart display mat that can receive a sensing signal detected by a transmitting terminal, and includes a display mat unit and a floor mat having a storage unit for accommodating the display mat unit. The display mat unit is provided with a concave groove on one side, and the concave groove is accommodated in a housing in which an accommodating portion for accommodating a power feeding module is correspondingly opened and an accommodating portion corresponding to the concave groove. A backlight module including at least one circuit board electrically connected to the module and having a plurality of light emitting members provided on the circuit board, and a back light module provided on the circuit board to receive a sensing signal from the transmitting terminal. A first wireless communication module provided on the circuit board, a gravity sensing module provided on the circuit board for detecting a change in acceleration and generating a voltage signal, and a backlight module provided on the circuit board to generate a voltage signal. 1 A first control module that is electrically connected to a wireless communication module and the gravity sensing module and turns on or off the backlight module based on the sensing signal and the voltage signal, and is housed in the concave groove and the back. It is provided with a top plate provided above the light module corresponding to it, and a bottom plate assembled on the other side of the housing and correspondingly covering the accommodating portion.

The transmitting terminal further includes a sensing module, a second wireless communication module, and a second control module, and the sensing module detects the sensing signal and transmits it to the second control module to control the second. The module generates a control signal from the sensed signal and transmits the control signal to the second wireless communication module.

Here, the floor mat of the present invention may be provided in the bottom of the vehicle body, and the transmission terminal may be provided in the scuff plate or the door of the vehicle body or the housing of the vehicle body.
According to the structure of the present invention, when the door of the vehicle body is opened, the sensing module of the transmitting terminal detects the opening of the door and the sensing signal, and transmits the sensing signal to the second control module. The second control module generates a control signal based on the sensed signal and transmits the control signal to the second wireless communication module. The second wireless communication module transmits a control signal to the first wireless communication module of the display mat unit, and the first wireless communication module transmits the control signal to the first control module when it is received. The first control module turns on the backlight module by a control signal. This allows the smart display mat to automatically turn on the backlight module when the door is open and turn off the backlight module when the door is closed. This avoids installation complexity and safety issues caused by the conventional floor mat and light emitting end being electrically connected to the vehicle power supply via the wire member. In the present invention, instead of the conventional connection by the electric wire member, the first wireless communication module of the smart display mat and the second wireless communication module of the transmitting terminal are adopted, so that the safety and mounting convenience are greatly improved, and the thickness is thin. Can be realized.

In addition, when the vehicle body is in a stopped state for a long time, the change in acceleration detected by the gravity sensing module of the display mat unit becomes 0, and the first control module sets the backlight module and the first wireless communication module by the voltage signal. By turning it off, the smart display mat is set to the power saving mode when the vehicle body is stationary, and only the gravity sensing module detects the operating state of the vehicle body.

On the other hand, when the vehicle body is in a running state, the change in acceleration detected by the gravity sensing module becomes larger than 0, and the first control module turns off the backlight module and the first wireless communication module based on the voltage signal. By doing so, the smart display mat is put into sleep mode when the vehicle body is running, and similarly, only the gravity sensing module is made to detect the behavior state of the vehicle body.

When the change in acceleration detected by the gravity sensing module changes from 0 to a value greater than 0 when the vehicle body door is opened or closed (that is, when the gravity sensing module changes from a stationary state to a vibrating state), the gravity sensing module The voltage signal is transmitted to the first control module, and the first control module controls the first communication module to be turned on for a certain period of time based on the voltage signal so that the control signal of the transmitting terminal can be received. As a result, the power saving effect can be achieved by turning off the unnecessary modules (backlight module, first wireless communication module) and setting the power saving mode or the sleep mode in either the stationary state or the running state of the vehicle body.

In addition, the display mat unit of the smart display mat is provided on the circuit board and further includes a first control module and a timer module electrically connected to the backlight joule. The power saving effect can be achieved by automatically turning off the backlight module by the timer module.

As shown in FIGS. 1, 2, and 3, the smart display mat 2 can receive the sensing signal detected by the transmitting terminal 8. The transmitting terminal 8 may be provided on a scuff plate, a related portion of the door 90, or a door frame 91 of the vehicle body 9 (see FIG. 6 for both). The smart display mat 2 includes a display mat unit 20 and a floor mat 7, and the floor mat 7 may be provided at the bottom of the vehicle body 9.

As shown in FIGS. 4 and 5, the display mat unit 20 includes a housing 201, a backlight module 22, a first wireless communication module 25, a gravity sensing module 26, a control module 27, a top plate 4, and a bottom plate. Includes 5 and. The housing 201 is provided with a concave groove 202 on one side, and an accommodating portion 203 is opened at a corresponding portion of the concave groove 202. The accommodating portion 203 accommodates the power feeding module 21. The power supply module 21 supplies electric power to each component of the display mat unit 20. The backlight module 22 includes at least one circuit board 24 housed in the recess 202 and electrically connected to the power supply module 21. The circuit board 24 is provided with a plurality of light emitting members 3, and these light emitting members 3 may be one of a light emitting diode or an organic light emitting diode. The first wireless communication module 25, the gravity sensing module 26, and the control module 27 are all provided on the circuit board 24 and are electrically connected to the circuit board 24. The first wireless communication module 25 receives the sensing signal from the transmitting terminal 8. The gravity sensing module 26 detects a change in acceleration and generates a voltage signal. The first control module 27 is electrically connected to the backlight module 22, the first wireless communication module 25, and the gravity sensing module 26. The first control module 27 turns the backlight module 22 on and off based on the sensing signal and the voltage signal. The top plate 4 is housed in the recess 202 and is provided above it corresponding to the backlight module 22. A translucent portion 40 is further formed on the top plate 4, and the translucent portion 40 is above the translucent portion 40 corresponding to the backlight module 22 so that the light rays from the light emitting member 3 can be emitted to the outside through the translucent portion 40. It is provided.

The bottom plate 5 is provided on the other side of the housing 201 and covers the accommodating portion 203. Further, a waterproof ring 6 is further provided between the bottom plate 5 and the housing 201, and the waterproof ring 6 is provided in the circumferential direction of the accommodating portion 203. As a result, the display mat unit 20 has a waterproof effect.

The floor mat 7 includes a storage unit 70 to which the display mat unit 20 is mounted. The floor mat 7 to which the display mat unit 20 is mounted may be provided around the undercarriage of the driver's seat, the passenger seat, or the rear seat in the vehicle body 9.

In this embodiment, the transmitting terminal 8 is described as being provided on the scuff plate, but the transmitting terminal 8 is not limited to this, and the transmitting terminal 8 is provided on the door 90 or the door frame 91 (as described in paragraph 0021). May be done. The scuff plate further includes a sensing module 80, a second radio communication module 81, and a second control module 82. The sensing module 80 may be either a magnetic proximity switch or a capacitive sensor, and uses a change in the detected charge instead of the conventional magnet form, and thus the vehicle body. The sensing function can be exhibited without installing a magnet on the door 90 of 9. It is a well-known technique to detect the opening or closing of the door 90 by using the sensing module 80 of the scuff plate, and therefore, it is not described in detail here. For the first control module 27 and the second control module 82, a microcontroller (MCU) or an integrated circuit (IC) may be selected.

As a result, when the door 90 is opened or closed, the sensing module 80 transmits the detected sensing signal to the second control module 82, and the second control module 82 generates a control signal based on the sensing signal. The control signal is transmitted to the second wireless communication module 81, and the control signal is transmitted to the first wireless communication module 25 of the display mat unit 20 via the second wireless communication module 81. This notifies the floor mat 7 of the current opening or closing of the door.

According to the structural design of the present invention, as shown in FIG. 6, when the door 90 of the vehicle body 9 is opened, the sensing module 80 of the transmitting terminal 8 detects that the door 90 is in the open state and detects the sensing signal. Then, the sense signal is transmitted to the second control module 82. The second control module 82 generates a control signal based on the sensed signal, and transmits the control signal to the second wireless communication module 81. Subsequently, the second wireless communication module 81 transmits the control signal to the first wireless communication module 25 of the display mat unit 20, and when the first wireless communication module 25 receives the control signal, it further transmits the control signal to the first control module 27. Then, the first control module 27 turns on the backlight module 22 based on the control signal. Therefore, according to the present invention, the smart display mat 2 can automatically turn on the backlight module 22 when the door 90 is opened and turn off the backlight module 22 when the door 90 is closed. Therefore, it is possible to avoid problems such as mounting complexity and safety that the conventional floor mat and the transmitting terminal must be electrically connected to the vehicle power supply via the electric wire member. In the present invention, the first wireless communication module 25 of the smart display mat 2 and the second wireless communication module 81 of the transmission terminal 8 are adopted instead of the conventional connection form by the electric wire member, so that the safety and convenience are greatly improved. The effect of thinning can be achieved.

In addition, when the vehicle body 9 is in a stopped state for a long time, the change in acceleration detected by the gravity sensing module 26 of the display mat unit 20 becomes 0, and the first control module 27 receives a voltage signal from the gravity sensing module 26. By turning off the backlight module 22 and the first wireless communication module 25 based on the above, the smart display mat 2 is set to the power saving mode when the vehicle body 9 is stationary, and only the gravity sensing module 26 detects the operating state of the vehicle body 9. To do so.

In addition, when the vehicle body 9 is in a running state, the change in acceleration detected by the gravity sensing module 26 becomes larger than 0, and the first control module 27 backlits based on the voltage signal from the gravity sensing module 26. By turning off the module 22 and the first wireless communication module 25, the smart display mat 2 is put into sleep mode when the vehicle body 9 is running, and similarly, only the gravity sensing module 26 is made to detect the operating state of the vehicle body 9. ..

When the acceleration detected by the gravity sensing module 26 changes from 0 to a value larger than 0 when the door 90 of the vehicle body 9 is opened or closed (that is, when the gravity sensing module 26 changes from a stationary state to a vibrating state), gravity sensing The voltage signal from the module 26 is transmitted to the first control module 27, and the first control module 27 turns on the first wireless communication module 25 for a certain period of time based on the voltage signal so that the control signal of the transmission terminal 8 can be received. It controls and turns on the backlight module 22 by the control signal. Therefore, when the vehicle body 9 is in a stationary state or a running state, the smart display mat 2 turns off unnecessary modules (backlight module 22, first wireless communication module 25) to enter a power saving mode or a sleep mode. Therefore, the energy saving effect can be achieved.
